Bowerick Wowbagger, known as Wowbagger the Infinitely Prolonged, is a tall, flat-headed, slitty-eyed creature with a lustrous sheen to his pale gray green alien skin that most pale gray green alien races can acquire only with plenty of exercise and very expensive soap. Immortality was inadvertently thrust upon him by an unfortunate accident with an irrational particle accelerator, a liquid lunch and a pair of rubber bands. No one has ever managed to duplicate the exact circumstances under which it happened, and many have ended up looking very silly, or dead, or both, trying.
Wowbagger despises immortality and decided to insult the universe, everyone in alphabetical order. He equipped a spaceship built to last with a computer capable of handling all the data processing involved in keeping track of the entire population of the universe and working out the horrifically complicated routes involved. He hopes that from some vantage point in the universe his connect-the-dots itinerary might be seen to spell a very, very rude word.
Wowbagger visited Arthur Dent after three years of the latter being stuck in prehistoric Earth, and called him a kneebiting jerk. He insulted Arthur Dent once again at Lords’ Cricket Ground after the Krikkit Droids’ attack, due to a time mix-up, as well as Genghis Khan, provoking him to burn down large segments of Asia. He finally reached the end of his list – the Great Prophet Zarquon, whom he had missed the first time around. Zarquon insulted him back and removed his immortality, killing him (to great applause).
